PRINTING-PRESS.

Specification of Letters Patent No. 19,672, dated March 23, 1858.

To all whom it may concern:

Be it known that we, HENRY A. BILLS and S. W. WOOD, of. Washington,District of Columbia, have invented certain new and useful Improvementsin Printing-Presses, of which the following is a full, clear, and eX-,act description, reference being had to the annexed drawings, makingpart of this specification.

Figure 1 represents a side elevation of our improved printing press withbut the two lower setof rotating, flat, type forms, the upper type formsto print the opposite side of the sheet or sheets being but duplicatesof the first set are not represented, not being deemed necessary here.Fig. 2 is an end elevation of Fig. 1 showing the gearing which connectsand imparts motion to the several parts. Fig. 3 is a side elevation of acylindrical type wheel or bed, with four columns of type secured theretothe columns being in section to show clearly the manner of keying in thetype. Fig. t'is a section of the stick or form for holding the type.Fig. 5 are side views of type showing the notch or groove by which theyare keyed or fastened to their form. Fig. 6 is a side elevation of aline of type representing them as being set upon a flat form with theirkey in position the two ends of said key extending so as to entergrooves formed in the column lines. Fig. 7 represents a stick or formfor holding type, detached; this form may contain type for a column andis secured to a rotating bed by nuts and bolts or in any otherconvenient manner. Fig. 8 represents the independent columns in separateand independent sticks or forms, secured to cylinders in the usual way;the opposite sides of the sheets being printed alternately. Fig. 9represents a modified form of feeding printing presses from a continuoussheet, said sheet having a continuous motion; the type for one side of asheet being locked into a form in the ordinary manner and secured uponthe periphery of a cylinder, the sheet in this case being severedprevious to being printed.

The nature of our invention consists first in setting type uponfiat,rotating forms or beds in separate and independent columns arrangedalternately upon the peripheries of cylinders, withcorresponding'cylinders upon whose peripheries are secured segments ofimpression cylinders which press upon the type always in a lineperpendicu' lar with their surfaces; said cylinders being gearedtogether by cog wheels of corresponding size rotate with the samevelocity. Second, in notching or grooving type so as to receive keysflush with their surfaces, the ends of said keys extending into groovesformed in the column lines, or secured to the bed or form in any otherconvenient manner.

' To enable others skilled in the art to make and use our improvedprinting press, we will proceed to a description of the same in detail.

Like letters indicate similar parts in all the figures.

A, in the accompanying drawings repre sents the frame the front or oneside being removed to exhibit the parts more distinctly, constructed ofany suitable material and in any desired form.

D, are rotating beds or forms composed of a suflicient number of fiatsurfaces (e), upon which the columns (0) are secured, tocorrespond withthe number of columns desired to print upon each sheet. To these flat'surfaces (e) the. sticks or forms (0) containing a column of type aresecured by nuts and bolts (a) or in any other convenient manner. Theseflat columns are secured alternately upon the many sided rotating bedsor forms (D) in order that straight type may be used, also that they maybe set in flat forms in the usual manner, instead of being set upon acylinder or in the arc of a circle. alternate column is printed by eachset of type, the first set or those nearest the roll (E) (or coil) ofpaper, leave every alternate column blank, which blank columns areprinted by the second set of type arranged alternate to the first.

To press the paper upon the type to leave their impression, a cylinder(M) of the desired diameter to correspond with the type forms or beds(D) is placed, for convenience in this instance, directly above the typeand supported in suitable bearings. Tothe periphery of this wheel orforming a part thereof, are secured segments of circles (0) arrangedalternately so as to correspond with the alternate columns of type;these segments of circles (0) correspond with the spaces (u) formed bysetting the columns of type in fiat beds or forms. Hence it will beseen, that as the paper is carriedthrough between the type'andwh'eels (Band by By this arrangement, every its margin, and middle if necessary,the segments (0) of the dotted circles (w) roll upon the faces of thecolumns of type always in a line perpendicular with their centers, andparallel with the shaft of the type.

To print both sides of a sheet by once passing through the press, asecond set of type in alternate columns, with their correspondingsegmental cylinders may be arranged, and which is our intention inconstruct-ing a press complete; a second set of cylinders and type beingbut a duplicate of the first, we do not deem a detailed description ofthem necessary.

The stick or form in which the type are secured may be made of anydesired dimensions, the type being secured thereinby wedges in the usualway or by keys with or without said wedges or they may be fused forminga solid mass upon the cylinder. To secure type in position by keys, ortheir equivalent, which is designed particularly when setting them upona cylinder or in the arc of a circle as shown in Figs. 8 and 9, thecolumn lines are grooved, see Figs. 3 and to receive the ends of saidkeys (S); the type (m) being notched as seen in Fig. 5, to receive thekeys flush withtheir surfaces. When columns are set in fiat forms asrepresented in Fig. 1, the type may be secured by wedges, or keys may beemployed if preferred, or fusing may be substituted.

To supply presses with paper, a roll (E) or it (the paper) may be coiledif preferred, of any desired size may be placed upon an endless belt (U)of felt, leather or other suitable material, which belt runs with thesame velocity as the type; if used from the coil a belt may be dispensedwith. The ends of the shaft passing through this roll of paper, extendinto slotted guides formed in the frame as seen in dotted lines behindthe roll (E) Fig. 1, which retains said roll in position, alwayspermitting it to remain in contact with the belt, (U) the friction ofwhich rotates said roll at the proper velocity regardless of its size.

To feed a continuous sheet of paper to a press where the type are setupon the periphery of a cylinder in the usual manner, that is, with one,'or more forms, containing a page of matter, the paper may be severedbefore entering the press, the supply being taken from the roll or coilat a rate that, at the time the type have made one revolution, andpresented themselves to print the succeeding sheet, the desired quantityof paper will have presented itself and the knife (P) will have severedthe sheet in time to allow the fingers (f) to seize the severed part andcarry it around the cylinder (to) to be printed; the paper from the rollor coil moving constantly. In Fig. 9, the paper, in red tion, we omitfurther mention of it here.

To dampen the paper to prepare it for the press, we have arranged awheel (I) which may be made of or covered wit-h any suitable material toabsorb moisture; this wheel is placed so as to roll upon the paper, andbeing supplied with moisture in any convenient manner, and running withthe same velocity as the paper, dampens it sufficiently and equally toreceive the desired impression. Several wheels may be arranged throughwhich the paper may pass if one be found insufficient, or if preferred,it may pass through steam to receive the required dampness; or, two ormore endless belts of felt or other suitable material to absorb moisturemay be employed; the paper being fed between these belts which aremoistened by moist rollers or in any other convenient way; rollers ortheir equivalents may be used to press these belts together upon thepaper if necessary, as seen in Fig. 1.0. To separate (or nearly so) theprinted matter into sheets, after or before being printed, we haveconstructed a revolving knife (P) which revolves once for every sheetand at the same velocity with the type, or at the speed required tosever the sheet in time to be, or after it has been printed. This knifemay sever the sheets entire, or may leave small parts uncut at the twosides or margin and in the'middle, in order to have sufficient strengthto re-roll the printed sheets as hereinafter described and shown in Fig.8.

J, represents an endless belt running at the same velocity with the typeand endless belt or belts (U), by which the paper is supplied. Theprinted sheets upon this end less belt (J) are re-rolled by itsfriction, being nearly severed by the rotating knife (P).

The rotating type beds, (D) the segmental cylinders, (M and B) therotating wheels carrying the knife, (P) the endless belt supplying thepaper from the roll or coil, the endless belt rolling up the printedsheets nearly severed, the cylinders or cylinder for dampening the paperand the ink roll for inking the type, all move with the same velocity,being geared together by cog wheels (T).

To print newspapers, the paper from the coil or roll passes beneath thedampening cylinder or between the damp, endless belts, thence over thefirst set of type where every alternate column is printed, thence overthe second set of type where the alternate columns, blank, are printedcompleting one side of the sheet, thence beneath a corresponding orduplicate set of type not represented, which print the opposite side,thence between the dividing knife (P) Where the printed sheets are (ornearly so) severed, and thence to the endless belt (J) Where they arere-rolled when the issue is ready for distribution.

When round cylinders are employed and the type secured upon theirperipheries, as seen in Figs. 8 and 9the type may be fused, instead ofkeying or Wedging them upon said cylinder or are of a circle, renderingthem a solid mass.

The manner of inking the type being no part of our invention, Werepresent a single roll (R) as being sufficient reference.

Having thus fully described our improved printing press, What We claimtherein as as set forth.
